In a mixing bowl, combine the key lime juice, sweetened condensed milk, heavy cream, and vanilla extract. Whisk until smooth and thoroughly blended.

Fold in the graham cracker crumbs, ensuring an even distribution throughout the mixture.

Use a silicone ice cube tray or mini muffin pan lined with mini cupcake liners. Spoon the key lime filling into each cavity, filling them about ¾ full. Smooth the tops with a spatula.

Cover the tray with plastic wrap and freeze the key lime bites for about 3 hours or until completely firm.

In a microwave-safe bowl, combine the chocolate chips and coconut oil. Heat in 30-second increments, stirring in between, until melted and smooth.

Once the key lime bites are firm, gently remove them from the tray. Dip each bite into the melted chocolate, allowing any excess to drip off.

Place the dipped bites back onto a parchment-lined tray and repeat until all bites are coated. Freeze for an additional 15-20 minutes to set.

Once the chocolate has set, your Chocolate Covered Frozen Key Lime Pie Bites are ready to serve. Enjoy these delightful treats cold!
